Application filed October 12, 1905. Serial N o. 282,440.

To all whom it 'may concern:

Be it known that we, PAUL SCHRAMM and IRA E. WisE, citizens of the United States, residents, the said SCHRAMM, of Alameda, Alameda county, State of California, and the said WISE, of IVallace, Calaveras county, invented a certain Explosive-Engines 5 declare the following to be a full, clear, and -exact description of the same.

new and useful Valve for Specification of Letters Patent.-

vOur invention relates .to an improved valve for explosive engines, whether vertical, horizontal or otherwise.

The objects of the invention are to revent clogging, obviate warping, and to redliice the number of parts.

Ou'r invention consists, in combination `chamber G. Around the lablyr secured th'e spring a',

with an explosive engine, of a chamber havbut -a single opemng for the admission of the explosivemixture, and for the esca e of the products of the explosion, and of a single. valve alternately opening and closing said l opening. v 5

Referring to the accompanying drawings- Figure 1 is a erspective view of our valve, disclosing the inlet and exhaust ports; spring by which the valve is held to its seat, and a two-lift cam. Fig. 2 is a sectional view of Fig. 1. Fig. 3 is an enlarged detail view of the valve-disk, neck, shoulder and stem. Fi 4 is an end view in elevation of Fig. 3 talen through 3 3', andrdisclosing the perforations through which the explosive mixture is admitted to the valve-chamber.

A .desi nates the valvecasing, Within which is sglidably secured the valve-stem A. Uponv the inner end of the valve-stem A', and made, referably, integral therewith, is the valvei'sk D, the neck E, and the bod F. The body F of the valve, having the Yperfigrations or channels F', which channels may be of any number orcharacter which will allow the explosive mixture to pass therethrough.

B is the inlet port, and C is the exhaust ort, which are alternately opened and closed by the o eration of the bodyof the valve.

G is -tlie valve-chamber, which is opened and closed byI the operation of the valve.

character best adapted to hold the valve to its seat.

H represents any suitable mounting for the stem A', which will hold the spring a in position. Within this mounting H, is secured the .roller H', which is adapted to come in contact with the two-lift cam'I.

L designates a part'broken view of a cylinder. l

The operation of our improved valve, lis as follows-The two-lift cam is rotated in any suitable manner, not necessary herein to show. The cam I bears upon the roller H', As the cam, point J, comes in contact with the roller H', the Valve is lifted, opening the chamber G, and allowing the previou'sly used charge to escape therefrom into the exhaust outlet C. During this movement of the valve, the inlet ort B is positively closed by the valve-bod y F. As the oint K, of the cam I, bears upon the roller H', time', the body F thereof positively closing the exhaust ort C, and opening the inlet port B, there y allowing the fresh explosive charge to enter the chamber G, through the perforations or channels F', and the same o ening a, as that through which the exp oded charge has just escaped. This operation is contlnuous and in' rapid succession. y

-By the use of our invention, but a single valve is .necessary to successfully operate the inlet and exhaust ports of an explosive engine.' Clogging is revented by tlm-.action of vthe cool fresh ex osive charge entering the valve-chamber tiirough the saine opening, (and in rapid succession) as that through which the used up charge escapes. The cooling action of the fresh ex plosive mixture upon 'the parts, also `keeps the same free from warping.

Having thus described. our invention, what We claim `as new and desire to secure by Letters Patent, is-v In an explosive engine, a valve chamber havin 'a single o ening communicating with the cy inder for t e entrance of the explosive mixture and for theexhaust of the products of combustion, and providedy with a single passage for theadinisson of the gaseous nuxture andA an exh aust passage communicating Vthe valve'is lifted a ser-ond Withsaid opening, and a single valve controllingsaid opening and passages.. said valve comprlsmg a head adapted-th `-ieat in the chanriber opening, Aand a hollbvcvlindrical bodyportion depending from said 4headand connected therewith by a -reduced portion arranged in one position of the valve to form aW direct communication exteriorily of `the valve between the cylinder and exhaust passageg-'s'aidreduced portion having ports therein 'adapted when the valve is moved to another position to establish a communication between the passage for the gaseous mixture and the cylinder through thevbody of the.10 i

valve, and means for actuating said valve.

In Witness whereof we have Ahereunto set our hands. PAUL SCHRAMM.
